plate. Valid for all enforcement events.
 Plate Matching Ratio: The matching ratio is the threshold for the camera to judge whether it
should save a group of captures or not. The camera compares the license plate numbers
within a group of captures and gives the current matching ratio. If the returned matching
ratio is higher than the set value, the camera saves the captured group. If you set the value
as 0, the camera will not compare license plate numbers among captures within a group.

information may be filtered out if the threshold is extremely high.
 Illegal Parking Plate Size Threshold: If the width of the captured plate is lower than the set
threshold, the plate will not be recognized. The lower the threshold is, the smaller plate will
be filtered out. It is recommended to keep the default value.

and trigger alarm.
